I would recommend not doing anything for free, but if you really want to, maybe cater family/friends’ events? If the family and friend has a large following on instagram on Tiktok, even better. They can post on their page and you can start getting followers. Samples may be ok, but you’re running a business and not a charity. I also feel it devalues the product. Social media presence for small biz is the way to go.
We usually try someone out for a month as an independent contractor before hiring. We also have a policy against using phones at work. We are a retail store. Phones are ok at lunch time, but otherwise they must be kept in their locker. If you don’t want ppl to use their phones, might be good to enforce a policy? Technically, they aren’t doing anything “wrong”. Also, have a conversation before firing them. They should have a right to know and time to correct their mistakes before getting fired.
